Actress Jenny McCarthy opened up recently to Cookie magazine, talking about life with boyfriend Jim Carrey, her 7-year-old son Evan and being an autism activist.

As far as adding to her brood or marriage -- McCarthy says no on both counts! The good thing, she admits, is that Carrey is in total agreement: "It's wacky-weird that not only does he not want to get married, which I love ... but he also doesn't want to have more kids, which I love."

McCarthy is happy to reveal that her son Evan, who was diagnosed with autism at age 2 1/2 -- is now symptom free. After initially being misdiagnosed with epilepsy, McCarthy was determined to learn all about autism -- and found aid through the advocacy organization Generation Rescue ( where she and Carrey now serve on the board of directors). "There wasn't anyone [in the medical community] talking about a gluten-free, casein-free diet in 2005," McCarthy tells the mag. "So in blind faith, I said, 'I'm going listen to other parents instead."

"In addressing physical ailments like epilepsy, leaky gut, candida [a yeast infection], bowel disease, and food allergies, as well as behavioral disorders, like ADHD and OCD, that are associated with autism," she explained, "we [parents at Generation Rescue] find that, along with those problems, the autism either gets better or goes away."

McCarthy also clears up the former press regarding her feelings about vaccinations and their connection to autism: "I think vaccines are one of the greatest things ever invented. Vaccinations are safe—dot, dot, dot—for some kids. Vaccinations are not safe—dot, dot, dot—for other kids. Let's protect the ones who are weak. We are pro–safe vaccine."
